The Shamuluo Formation of Upper Jurassic in Dongqiao is mainly composed of a series of tidal flat and carbonate platform deposits and especially characterized by a lot of organic reefs. Reef-building organisms are chiefly Stromatoproids, and secondly hexacorals. Through the study of individual ecology and analysis on the assemblage of reef-building organisms, three reef-building communities are recognized, namely Milleporidium-Cladocoropsis, Cladocoropsis-Milleporidium-Milleporella and Milleporidium-Actinatraea community. The analysis of sea-level changes indicate that it exists three sea-level change cycles of the reef-bearing strata in the study areas, among them, the first cycles developed in the lower section of the Shamuluo Formation, namely clastic rocks Member.
